NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 771,139, datedSeptember 27, 1904. Application filed February 8, 1904. Serial No.192,608. (No model.)

To all whom it may concern:

Be it known that I, CHARLES BROUGH FUDGE, a citizen of the UnitedStates, residing at Mun cie, in the county of Delaware and State ofIndiana, have invented certain new and useful Improvements in Nut-Locks;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention is an improved nut-lock; and it consists in theconstruction, combination, and arrangement of devices hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is partly a longitudinalsectional view and partly an elevation of a nut, bolt, and locking-plateproviding a nut-lock embodying my improvements. Fig. 2 is an endelevation of the same. Fig. 3 is a transverse section taken on the planeindicated by the line a a of Fig. 2. Fig. 4 is an end elevation of amodified form of nut-lock embodying my invention; and Fig. 5 is atransverse sectional view of the same, taken on the plane indicated bythe line 5 Z) of Fig. 4.

The bolt 1, on which the nut 2 is secured, has its threaded stemprovidedwith an angular portion 3, which is here shown as at its outerend. The nut, which engages the screwthreaded portion of the bolt-stemin the usual manner, is provided on its outer side with flange-lugs 4.Three of these lugs are shown in Fig. 2, one of them at one side of thenut and the others at the opposite side thereof and appropriately spacedapart.

In connection with the bolt and the nut there is a lock -plate 5, whichis made of spring-steel, has an angular opening 5 of size and shape toadapt it to receive the angular portion 3 of the bolt-stem, and the saidlockplate is split at one end, as as 7 and provided with arms 8, whichby the spring energy of the lock-plate are moved apart laterally andengage normally with the pair of lugs at one side of the nut, as shownin Fig. 3. The integral end of the lock-plate is here shown as notched,as at 9, and engaged with the flangelug at the opposite side of the'nut.The ends of the arms 8 project beyond one side ofthe nut and may beturned at right angles, as here shown. These projecting ends of the armsmay be engaged by means of a pair of pincers and compressed so as tomove the arms 8 toward each other, and thereby release them from thecoacting pair of flange-lugs, and thus enable the lock-plate to bedetached from the nut, as will be understood.

In the form of my invention shown in Figs. 4 and 5 the nut is providedwith a pair of oppositely-disposed flange-lugs 10, and the lockplate 11has an angular opening 12 therein formed between a pair of parallel arms13, the outer sides of which are flush with those of the plate, theplate being longitudinally movable aross the face of the nut to engageit with the flange-lugs and the angular portion of the bolt-stem and toenable it to be moved in the opposite direction to disengage it from theflange-lugs and the bolt-stem. The length of the arms is such that theirouter ends may be bent at right angles when the nut is locked on thebolt-stem by the lock-plate, so that the said bent ends bear against oneside of the nut to prevent the lock-plate from becoming casuallydetached therefrom.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the prin ciple orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination ofa bolt having its threaded stem provided with across-sectionally angular projection, a nut engaging the threaded stemand having on its outer side flange-lugs, which are recessed in theiropposing sides, and a lock-plate having an angular opening to receivethe angular projection of the stem, having one end engaged with thenotch of one of the flange-lugs of the nut, and

having a pair of spring-arms, movable toward and from each other, saidspring-arms extending between and engaging notches in a pair of theflange-lugs, substantially as described.

2. The combination of a bolt having its threaded stem provided with anangular portion, a nut engaging the threaded stem and having flange-lugson its outer side, and a spring lock-plate on the nut having an angularopening through which the angular portion of the bolt extends, saidlock-plate being further provided at one end with laterallyspaced armsextending from the opening, engaging the flange-lugs and detachabletherefrom to release the bolt by laterally pressing the said arms towardeach other.

3. The combination of a bolt having its threaded stein provided with anangular portion, a nut engaging the threaded stern and havingflange-lugs on its outer side and a spring lock-plate on the nut havingan angular opening through which the angular portion of the boltextends, said plate being provided at one end with laterally-spaced armsextending from the opening and engaging certain of the flange-lugs anddetachable therefrom by pressing the said arms toward each other, theother end of the lock-plate engaging the other lug of the nut,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
